• Flow rate: 500 ml/min
• Voltage: 230V / 50Hz
• Power: 18W
• Reservoir capacity: 1.3 litres
• Outlet: 12mm push-fit
• Alarm: Audible and visual high-water-level alarm
• Country of origin: United Kingdom

Compatible Systems:

• Wall-mounted split AC units
• Ceiling cassette units
• Ceiling concealed and ducted units
• Multi-split indoor units
• VRF/VRV systems
• Fan coil units (FCUs)

Compatible Brands: Suitable for use with Daikin, Mitsubishi Electric, Fujitsu, Panasonic, Samsung, LG, Hitachi, Toshiba, and most other AC brands.

When to Use This Pump:

• Ideal when gravity condensate drainage is not possible due to installation height or building layout.
• Suitable for ceiling cassette installations where the drain outlet sits below the building waste pipe.
• Use where a high condensate volume is expected — the 1.3 litre reservoir accommodates variable flow rates from larger systems.
• Suitable for commercial installations requiring a reliable, alarmed pump with audible and visual high-water alert.

Frequently Bought With:

• Castel DH-ADP96 Flexible Condensate Drain Hose 16/18/20mm – 50m Coil — standard drain hose for condensate pump installations
• Flexible Condensate Drain Pipe 16mm 50m — direct-fit 16mm drain pipe
• Jubilee Clip 9-12mm — for securing the 12mm outlet hose connection
• Sauermann Tee Connectors 6mm – Pack of 5 — for multi-unit condensate drain runs

Frequently Asked Questions:

Can this pump be used with a Daikin ceiling cassette?

Yes. The MaxiBlue X87-701 is suitable for ceiling cassette installations where the condensate drain outlet sits below the building waste pipe. Check the required lift height against the 10m max head specification.

What is the difference between the X87-701 and a mini condensate pump?

The X87-701 is a reservoir (tank) pump with a 1.3 litre capacity, designed for larger systems or installations with variable condensate flow. Mini pumps are better suited to smaller wall-mounted splits with lower condensate volumes.

Does this pump include a high-level alarm?

Yes. The X87-701 includes both an audible buzzer and a visual indicator that activate when the reservoir reaches high-water level, providing a safety alert before overflow occurs.

What pipe size does this pump connect to?

The outlet accepts 12mm push-fit condensate drain hose, compatible with standard HVAC condensate drain pipe.

Is this pump suitable for R32 systems?

Yes. The pump handles condensate water only and is refrigerant-agnostic — compatible with R32, R410A, R22, and all other common refrigerants.
